Congrats on passing and I hope your hakama fits.
I trip on mine in iaido (only yudansha wear hakama in my dojo for aikido). I have conceded that I will more then likely tuck my hakama up into the himo for a capri version of a hakama when I am forced against my will to wear one. Luckily for me, that is a LONG way off.
Also, like everyone else said, tie your hakama and belt wherever you need to. It is something men just don't understand. Their boxy frames suit tying it in that location rather well and some men in my dojo have a tiny tummy and that keeps it down even more
